A shooting star is a meteor that burns up when it reaches Earth's
atmosphere. Many of these meteoroids are quite small. Calculate the
kinetic energy of a meteoroid of mass 5.0 g moving at a speed of 45
km/s and compare it to the kinetic energy of a 1200-kg car moving
at 29 m/s (65 mi/h).
A. meteor_______ MJ
B. car________MJ
